I don't think these questions have been properly answered: Who in the Executive branch of the United States government set up and launched the plan to embarrass gun-rights supporters through the deployment of the infamous scheme that's come to be known as "Fast and Furious"? And who authorized it?

Executive privilege, so you know, can only be invoked if the White House chooses to protect the President and his correspondence from Legislative overreach. But the President has told us that he never had anything to do with "Fast and Furious." So how does his invoking executive privilege apply? Did he have something to do with it after all?

That leaves the big question: What did Obama know and when did he know it?
